Rigol DG800 Series Arbitrary Waveform Generators are 1-2 channel, 10-36MHz high-resolution (16bit) signal generators with up to 8 Mpts waveform memory.
These units appear to me using same hardware (just different color chassis) and firmware as Rigol DG800 Series signal generators.
Devices
Hardware on all these models is identical, only difference is in software/firmware.
| Model | Channels | Max Frequency (Sine) | Max Frequency (Square) | Arbitrary Waveform Length | Frequency Counter |
|---|---|---|---|---|---|
| DG811 | 1 | 10 MHz | 5 MHz | 2 Mpts | Y |
| DG812 | 2 | 10 MHz | 5 MHz | 2 Mpts | Y |
| DG821 | 1 | 25 MHz | 10 MHz | 2 Mpts | Y |
| DG822 | 2 | 25 MHz | 10 MHz | 2 Mpts | Y |
| DG831 | 1 | 35 MHz | 10 MHz | 2 Mpts | Y |
| DG832 | 2 | 35 MHz | 10 MHz | 2 Mpts | Y |
- ) Waveform memory can be upgraded to 8 Mbpts via software license.

Example use
Depending on your type of connection you have to can either use the USBTMC connection parameter or the TCP/IP connection parameter. Examples:
-d rigol-dg
(usually no parameters are needed when connecting via USB)
When connecting over TCP/IP need to specify ip address and port:
-d rigol-dg:conn=tcp-raw/192.168.42.42/5555
Check the capabilities of the meter's driver, and current state of settings:
$ sigrok-cli -d rigol-dg --show
Check the capabilities specific to a channel (1 or 2):
$ sigrok-cli -d rigol-dg -g 1 --show
Enable or disable channel output (first channel):
$ sigrok-cli -d rigol-dg -g 1 --set --config enabled=true $ sigrok-cli -d rigol-dg -g 1 --set --config enabled=false
Get or set the waveform function (second channel):
$ sigrok-cli -d rigol-dg -g 2 --get pattern $ sigrok-cli -d rigol-dg -g 2 --set --config pattern=square
Get or set the output signal frequency:
$ sigrok-cli -d rigol-dg -g 1 --get output_frequency $ sigrok-cli -d rigol-dg -g 1 --set --config output_frequency=20000
Get or set the output signal amplitude:
$ sigrok-cli -d rigol-dg -g 1 --get amplitude $ sigrok-cli -d rigol-dg -g 1 --set --config amplitude=3.3
Get or set the output signal offset:
$ sigrok-cli -d rigol-dg -g 1 --get offset $ sigrok-cli -d rigol-dg -g 1 --set --config offset=1.0
Get or set the output signal phase:
$ sigrok-cli -d rigol-dg -g 1 --get phase $ sigrok-cli -d rigol-dg -g 1 --set --config phase=90.0
Get or set the output signal duty cycle:
$ sigrok-cli -d rigol-dg -g 1 --get output_duty_cycle $ sigrok-cli -d rigol-dg -g 1 --set --config output_duty_cycle=25.0
Acquire measurement data (frequency counter output):
$ sigrok-cli -d rigol-dg --continuous $ sigrok-cli -d rigol-dg --time 10s $ sigrok-cli -d rigol-dg --samples 10
